Document Summary
Lecture content from lecture 2 - 24 (no content for lecture 1) Ecology - the study of the interactions that exist between an organism and other organisms as well as the interactions between the organism and its physical environment. Two species that live in a given area may have no direct influence on eachother. But they are connected to aspects of their environment . They are using the same physical space but might not necessarily have a direct influence on eachother. So even if two species do not interact directly with eachother, they can be connected indirectly by shared features of their environment. If the two species do not live in the same area then they are not indirectly or directly interacting. Amphibians can be considered biological indicators of environmental conditions. 1980s - found that deformed amphibians contain a parasite (flatworm) To test this: implanted small glass beads near developing limb bus of tadpoles.
